Safe and arm system for a robot
First Claim
1. A safe and arm system comprising:
- an operator subsystem including;
a first arm switch,a second arm switch, anda fire switch; and
a fire control subsystem responsive to the control subsystem and including;
at least a pair of terminals for connection to a munition, the terminals initially shorted together and without a ground,a power supply control circuit configured to supply power to the terminals,a ground supply circuit configured to ground one said terminal, anda terminal shorting circuit configured to remove the short across the pair of terminals,the power supply control circuit, ground supply circuit, and terminal shorting circuit configured to ground one terminal, remove the short across the pair of terminals, and to supply power to the terminals only if the first and second arm switches and the fire switch are all activated in a predetermined sequence.

Abstract
A safe and arm system includes an operator subsystem including a first arm switch, a second arm switch, and a fire switch. A fire control subsystem is responsive to the control subsystem and includes at least a pair of terminals for connection to a munition. The terminals are initially shorted together and without a ground. A power supply control circuit is configured to supply power to the terminals. A ground supply circuit is configured to ground one said terminal. A terminal shorting circuit is configured to remove the short across the pair of terminals. The power supply control circuit, the ground supply circuit, and the terminal shorting circuit are configured to ground one terminal, remove the short across the pair of terminals, and to supply power to the terminals only if the first and second arm switches and the fire switch are all activated in a predetermined sequence.

9. A method of safely and securely initiating munition connected to a pair of terminals, the method comprising:
-
initially shorting the terminals together; initially removing any ground from the terminals; initially providing no power to the terminals; connecting the munition to a pair of terminals; and removing the short across the terminals, supplying a ground to one terminal, and providing power to the terminals to initiate the munition only if three activations occur in a predetermined sequence. - View Dependent Claims (10)
